Why do you think there are earthquakes in mid-America where there are no known fault lines?

1 answer:

7 0

Earthquakes are mainly known to occur at plate boundaries where plates converge, diverge or slide past each other. Earthquake activity sometimes accompany volcanic eruptions but these too are concentrated around some plate boundaries (convergent, divergent).

Smaller earthquakes are known to occur in intra-plate regions, away from margins. These occur simply because of stresses being built up in rocks. The crust is solid and rigid and it floats on the mantle which is a curved surface like the crust.

Trava [24]

Answer:

There was no change in the number of days with poor flower availability

Explanation:

When replicating a study, the researcher develops the exact same study (experiment/treatment) in different places (experimental unit). In this case, as the researcher replicates the study in the Appalachian Mountains and gets similar results, that means that there was no change in the number of days with poor flower availability.

The secretion of a signal molecule by a cell into the local environment

Elodia [21]

Answer:

paracrine signaling.

Explanation:

Chemical signaling between cells is one of the most important ways that activities of tissues and organs are coordinated. The nervous system is the other major coordinating system in animals, but even here chemical signaling is used between adjacent neurons. The mechanisms involved are described as either being paracrine, autocrine, intracrine, endocrine, neuroendocrine or pheromones. Paracrine signals diffuse locally and act on neighboring cells.

In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cro

Aleksandr [31]

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

hetero-zygous. tall wrinkled (Ttrr)

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

Foiled genotypes (Tr, tr, each with 50%)

short hetero-zygous. round (ttRr)

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

Foiled genotypes (tR, tr, each with 50%)
